- an embodiment of a respiratory mask according to the disclosure includes a mask frame 10 and a soft mask pad 20 that has a rear end configured to contact a patient's face and a front end opposite to the rear end.
- the mask frame 10 can be provided with an air duct 30 and a pair of strap-connecting members 40 , which are not the essential feature of the disclosure and can be selected by a person skilled in the art, and thus, the detailed description thereof is omitted herein.
- the mask frame 10 is made of a rigid plastic material, and includes a ring-shaped base 11 , and a pair of wing portions 12 which are respectively connected at two opposite sides of the ring-shaped base 11 .
- the ring-shaped base 11 is disposed at the front end of the mask pad 20 , and has an inner periphery 111 , an outer periphery 113 surrounding the inner periphery 111 , and a tubular insert portion 112 protruding rearwardly from the inner periphery 111 to extend into the mask pad 20 .
- the two wing portions 12 are connected to the outer periphery 113 at the opposite sides of the ring-shaped base 11 and project rearwardly to respectively extend over two opposite sides of the mask pad 20 .
- Each of the wing portions 12 includes a connecting segment 121 connected to and extending rearwardly from the outer periphery 113 of the ring-shaped base 11 , and a support segment 122 connected transversely to and extending rearwardly and upwardly from the connecting, segment 121 and thus forming an L-shape with the connecting segment 121 .
- the support segment 122 is formed with a free end face 123 that has a positioning notch 124 indented from the free end face 123 , which is convexed and has a lower end 125 proximate to the positioning notch 124 , and an upper end 126 higher than the lower end 125 .
- the free end face 123 extends curvedly from the lower end 125 to the upper end 126 , and the upper end 126 is inclined in a direction toward the ring-shaped base 11 .
- the mask pad 20 is made of a silicone material that can undergo flexural deformation to bear a cup-like shape, and is installed on the mask frame 10 . Further referring to FIG. 3 , the mask pad 20 includes a front wall 21 , a sleeve portion 22 , a surrounding wall portion 23 , a facial sealing pad portion 24 and an abutting portion 25 .
- the front wall 21 has a bottom surface 211 sealingly abuts against a rear surface of the ring-shaped base 11 , and an inner peripheral edge defining an opening for extension of the tubular insert portion 112 of the ring-shaped base 11 .
- the sleeve portion 22 extends rearwardly from the inner peripheral edge of the front wall 21 and sleeves around the tubular insert portion 112 of the ring-shaped base 11 .
- the surrounding wall portion 23 rearwardly extends from an outer periphery of the front wall 21 around the sleeve portion 22 , and has an outer surface 231 over which the wing portions 12 extend, and a pair of protrusions 232 protruding oppositely from the outer surface 231 for respectively engaging the positioning notches 124 .
- the facial sealing pad portion 24 is disposed rearwardly of the surrounding wall portion 23 and opposite to the front wall 21 , and has a thickness less than that of the surrounding wall portion 23 .
- the abutting portion 25 obliquely extends from the surrounding wall portion 23 to the facial sealing pad portion 24 , and has a thickness that gradually decreases from the surrounding wall portion 23 to the sealing pad portion 24 .
- the abutting portion 25 has two outer surface regions 251 that respectively face the wing portions 12 and that diverge outwardly from the surrounding wall portion 23 to the facial sealing pad portion 24 .
- Each of the outer surface regions 251 has a curvature matchable with that of the free end face 123 of the support segment 122 of the corresponding wind portion 12 .
- Each of the outer surface regions 251 has a first site 252 proximate to a corresponding one of the protrusions 232 , a second site 253 spaced angularly from and located above the first site 252 , and a bordering end 254 adjoining the surrounding wall portion 23 , and forms an included angle with respect to a line parallel to an axis (L) of the tubular insert portion 112 and the sleeve portion 22 .
- the included angle gradually increases from the first site 252 to the second site 253 . Referring to FIGS. 5 and 6 , a first angle ⁇ 1 formed between the first site 252 and the line parallel to the axis (L) is smaller than a second angle ⁇ 2 formed between the second site 253 and the line parallel to the axis (L).
- the mask pad 20 is transformable between a non-sealing state and a sealing state. As shown in FIGS. 3 through 6 , after the embodiment of the respiratory mask is fully assembled, the facial sealing pad portion 24 can be placed outside the nose portion of a user without any deformation.
- the mask pad 20 Before transfer of pressurized air into the respiratory mask through the air duct 30 , the mask pad 20 is in the non-sealing state, in which the outer surface regions 251 of the abutting portion 25 are separated from the free end faces 123 of the wing portions 12 (i.e., having no physical contact with the free end faces 123 ), and the bordering end 254 is spaced apart from the free end face 123 of a corresponding one of the wing portions 12 with an interval of not less than 2 mm in this embodiment.
- the pressurized air would cause the surrounding wall portion 23 , the facial sealing pad portion 24 and the abutting portion 25 to inflate, especially the outer surface regions 251 of the abutting portion 25 , which would respectively abut against the free end faces 123 of the wing portions 12 .
- the mask pad 20 besides being able to remain stably mounted onto the user's face, would develop a buffer effect against deformation caused by the pressurized air, thereby ensuring quality air delivery to the user. Also, given that the bordering end 254 is originally spaced apart from the free end face 123 of a corresponding one of the wing portions 12 with an interval of not less than 2 mm, the abutting portion 25 would have more flexibility in deformation.
- the deformation capability of the abutting portion 25 corresponding to the second site 253 is better than the one corresponding to the first site 252 , thereby ensuring that the facial sealing pad portion 24 is securely fastened to the nose bridge of the user.
